Debian Science Image analysis packages

Gwyddion er et modulopbygget program for skanning (Skanning Probe Mikroskopi, SPM), samt visualisering og analyse af data. Det er primært beregnet til analyse af højdefeltdata indhentet via mikroskopiteknikker som

• Atomar Force Mikroskopi (AFM),
• Magnetisk Force Mikroskopi (MFM),
• Skanning Tunneling Mikroskopi (STM),
• Nær-felt Skanning Optisk Mikroskopi (SNOM eller NSOM) og andet. Det kan dog bruges til vilkårlige højdefelter og til billedanalyse.

Denne pakke indeholder det primære program og dets moduler. Den indeholder også en GNOME (og Xfce) miniaturefremstiller som opretter forhåndsvisninger af alle kendte filtyper til Gwyddion.

libCVD is a very portable and high performance C++ library for computer vision, image, and video processing. The emphasis is on providing simple and efficient image and video handling and high quality implementations of common low-level image processing function. The library is designed in a loosely-coupled manner, so that parts can be used easily in isolation if the whole library is not required. The video grabbing module provides a simple, uniform interface for videos from a variety of sources (live and recorded) and allows easy access to the raw pixel data. Likewise, the image loading/saving module provides simple, uniform interfaces for loading and saving images from bitmaps to 64 bit per channel RGBA images. The image processing routines can be applied easily to images and video, and accelerated versions exist for platforms supporting SSE.

This package contains tools and utilities using libcvd.

Teem er en koordineret gruppe af biblioteker til at repræsentere, behandle og visualisere videnskabelige rasterdata. Teem inkluderer værktøjer for kommandolinjen, som tillader at biblioteksfunktionerne hurtigt kan anvendes på filer og strømme, uden at der skal skrives kode. De mest vigtige og nyttige biblioteker i Teem er:

• Nrrd (og kommandolinjeværktøjet unu oven på) understøtter en bred vifte af operationer til at transformere N-dimensionelle rasterdata (resample, crop, slice, project, histogram etc.) samt NRRD-filformatet for lagring af tabeller og deres metainformation.
• Gage: Hurtig convolution-baserede målinger ved arbitrære punktlokationer i diskenhedsdatasæt (skala, vektor, tensor, etc.).
• Mite: En flertråde ray-casting diskenhedsoptegner med overførselsfunktioner baseret på enhver mængde som Gage kan måle
• Ten: til at estimere, behandle og visualisere diffusion tensor-felter, inklusive fibertraktografimetoder.

Denne pakke indeholder nogle simple værktøjer for kommandolinjen, som tilbyder hurtig og nem adgang til funktionaliteten i diverse biblioteker.

A collection of programs for images that are generated during a Particle Image Velocimetry (PIV) experiment. This is a technique to obtain the velocity field of a fluid flow quantitatively and is performed by tracking tracer particles that have been seeded to a fluid. The technique is also applied for observing deformations at surfaces of (solid) bodies. The package contains:

an image processing program for typical filtering and manipulation routines that may be convenient for PIV.

an image interrogation program resulting into estimators of particle image displacements.

validation programs to test on outliers, peak-locking effect and velocity gradients.

post-processing programs for data manipulation (flipping, rotation etc), spatial and time scaling, calculation of spatial averages and derivative quantities from the PIV data, like vorticity and strain.

miscellaneous programs and scripts to perform image format conversion, batch-processing, pipeline processing (image evaluation, validation and post-processing at once), calculation of time averages from a series of PIV data sets, data-visualization and data-manipulation.

All programs start with gpiv_.

This package contains all files used by gpivtools and gpivtools-mpi, like the man pages.
